/* This comment is a kludge to get metaconfig to see the symbols
VAL_O_NONBLOCK
VAL_EAGAIN
RD_NODATA
EOF_NONBLOCK
and include the appropriate metaconfig unit
so that Configure will test how to turn on non-blocking I/O
for a file descriptor. See config.h for how to use these
in your extension.
While I'm at it, I'll have metaconfig look for HAS_POLL too.
